Q1. Nine persons were born on the same date and month in different years, i.e., 1968, 1970, 1972, 1975, 1978, 1983, 1989, 1998, and 2009. Their ages are calculated as per the base year 2025. L is three years older than K. Only one person was born between L and M. R is two years younger than M. More than three persons were born between M and F. H is immediately younger than A. A is three years older than D. S is not older than F. What is the sum of the ages of H, F, and K?
- 135 years
- 148 years
- 129 years
- 128 years
Answer: 128 years
The given birth years correspond to ages 57, 55, 53, 50, 47, 42, 36, 27, and 16 in 2025. Using the clues, the only consistent placement gives H = 50, F = 42, and K = 36. Their sum is 50 + 42 + 36 = 128.
